SPECIFICATION forming part of Letters Fatent No. 681,404, dated August 2'?, 1901.

Application led February 27,1901. Serial No. 49,116. (No model.) i

To all whom, t 11i/ty concern:

Beit known that I, BENJAMIN BoswELL BARBER, a citizen of the United States, and

a resident of Baltimore, in the State of Maryland, and whose postofice address is 209 East German street, said city, have invented certain new and useful Improvements in Window-Sash Fasteners, of which the following is a specification.

My invention relates to window-fasteners; and it consists of means whereby the window may be locked securely against vertical movement and at the same time against lateral movement.

The object of my invention is to construct a device of this character that will be a combined lock and antirattler; and with this object in view myinvention consists of the parts and combination of parts, as will be hereinafter more fully set out.

In the drawings, Figure 1 is a perspective view of a window broken away with my invention attached. Fig. 2 is a side elevation of my invention attached to a window-frame, the latter being in section. Fig. 3 is a cross- Fig. 4 is a side elevation of my invention, parts broken away. Fig. 5 is a perspective view of a slight modification. Fig. 6 is a perspective view of the lower catch, the parts being separated.

1 represents a window-frame of approved construction, and 2 the sash thereof, which in the present instance is represented as the lower sash.

3 is a hat bead secured around the windowframe on the inside, against which the sash slides in its vertical movement.

4 is a bar which may be of any suitable length and secured to the beading 3 by means of suitable screws 5, said bar being provided throughout its length in one edge with notches 6.

7 is a plate having suitable screw-openings 8, by means of which said plate is secured to the bead immediately below the notched bar 4, as shown in Figs. 1 and 2..

9 is a lug or projection integral with the plate 7, having the cam-face 10, and 11 is a laterally-extending lug or projection eX- tending from one of the edges of the plate, as clearlyT shown in Fig. 6.

12 is another member of my locking device, provided with the dogs or ears 13, parallel with each other and having a suitable opening or perforation 14.

15 is a groove formed in the inner face of the member 12 and provided with a camwall 16.

17 are screw openings formed entirely through the member 12 or lug extensions at top and bottom of the same, through which suitable screws 18 pass to secure said member to the window-sash, as shown in Fig. 1.

19 is a dog having an ear or lug 2O provided with a suitable perforation 21, said lug being adapted to be pi voted between the ears or dogs 13 of the member 12 by means of the pivot-pin 22. The dog 19 is provided with an L-shaped projection 23, said projection extending inwardly from the face of the dog and to one side thereof, as at 24, as clearly shown in the drawings.

The parts being assembled as shown in Fig. 1, the operation of the device will be as follows: When it is desired to raise the window, the dog 19 is pulled outward, thereby disengaging the projection 24 from thelower face of the member 7, whereupon the window is free to be raised to the desired height, in

which position it is held by the engagementl of the projection 24 with one of the notches 6, into which it falls by gravity by reason of the weight of the dog being to one side of the center of its pivot. dog is disengaged from the notch 6 in the bar 4 and the sash permitted to be lowered. As soon as the cam-groove 16 of the member 12 begins to engage the cam-wall of the lug 9 on the plate 7 said cam-wall 10 of the lug 9 draws the sash snugly against the bead 3, and as soon as the projection 24 is passed below the plate 7 the dog 19, by reason of gravity, drops in under said plate, whereby the window, by reason of the engagement of the L- shaped projection 23 with the lower edge of the plate 7, is locked against vertical movement. The window is also securely locked against lateral movement by reason of the engagement of the cam-lug 9 onA the plate 7 with the cam-groove 15 on the member 12. Thus it will be seen that I provide by my invention a cheap, simple, and effective combined lock and antirattler for windows. It

To lower the sash, the

IOO

is obvious, of course, that the bar 4L and the plate 7 maybe cast integral with each other, and in some cases this will be preferable.

Having thus fully described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

l. In a window-fastener, the combination with a notched bar, a plate secured below the same, a projection integral with one edge of the plate, of a plate secured to a sash, and a dog pivoted to said member adapted to engage the projection on said plate and the notches in said bar and cooperating cams formed on the respective plates.
